Navigation Grade TDFG98T Fiber Optic Gyroscope
1 Introduction
The fiber optic gyroscope (FOG) functions as an angular velocity sensor utilizing the optical Sagnac effect. Its internal advanced all-digital closed-loop control architecture enables real-time transmission of carrier angular velocity data via serial communication interfaces. In inertial navigation systems, three orthogonal single-axis high-precision FOGs or a single integrated triaxial FOG configuration serve as core sensing components, detecting angular velocity parameters of moving platforms along three mutually perpendicular axes relative to inertial space.
2 Application
It is suitable for inertial navigation equipment and attitude reference equipment in the fields of guided weapons, aircraft, vehicles, ships, submersibles, orbit detection and medium and high-end industry.
